RESUMO
OBJECTIVE: Antipsychotic drugs constitute the basis of schizophrenia therapy; however, available pharmaceutical agents lack efficacy for treating the cognitive deficits caused by the illness. The aim of the present work is to present current data regarding cognitive rehabilitation of schizophrenia, providing information and guidance to health professionals. METHOD: A literature search was conducted in the PubMed and Google Scholar Databases from inception up to 1/9/2022. Relevant articles were explored for factors affecting cognitive function, including genetics, psychopathology, time in the course of the illness, and drug therapy. Characteristics and outcome of cognitive rehabilitation programs are briefly presented. RESULTS: A total of 562 relevant articles were retrieved, 39 of which were selected for the review. Factors contributing to a favorable outcome are young age, early phase of disease, symptomatic control of hostility and conceptual disorganization, lack of negative symptoms, management of drug side effects, and cognitive and cortical reserve. Some evidence for a procognitive effect seems to exist for atypical antipsychotics, clozapine, aripiprazole, memantine, modafinil, d-serine, and cycloserine. The Val/Val polymorphism of the COMT gene seems to be associated with worse outcome. Specific remediation strategies include programs such as Cognitive Enhancement Therapy (CET), Cognitive Adaptation Training (CAT), and RehaCom Cognitive Therapy Software, among others, all employing a range of techniques, from paper-and-pencil to computer-assisted, bottom-up, or top-down approaches, and varying neurocognitive targets. CONCLUSION: Cognitive symptoms, closely related to functional impairment, still remain a therapeutic challenge. Cognitive rehabilitation strategies are as yet the only treatment modality offering cognitive improvement to patients who struggle to recover.

BACKGROUND: Families of individuals with psychotic disorders are playing a major role in the care of their relatives, but report poorer physical competence, elevated symptoms of psychological distress and more psychopathological characteristics. AIM: To compare psychopathological characteristics demonstrated by caregivers of psychotic patients in Greece who participated in support groups organized by non-governmental mental health organizations (NGOMH) compared to caregivers who did not. METHODS: Participants were caregivers of a psychotic patient assigned to either the intervention group (n = 165) or the non-intervention group (n = 345) according to specific criteria. Participants were assessed for psychopathological characteristics through clinical interviews and with the Symptom Checklist 90-Revised (SCL-90-R). RESULTS: Participants who did not take part in the support groups had higher levels of psychopathological characteristics on the dimensions of interpersonal sensitivity (t = -2.065, p = .003), depression (t = 1.043, p = .007), anxiety (t = 1.001, p = .010), hostility (t = -4.345, p < .001), phobic anxiety (t = -2.845, p < .001) and paranoid ideation (t = -1.091, p < .001). Psychotic relatives of participating caregivers show higher compliance rates in taking their medications, and female caregivers tend to be more involved in the support groups. CONCLUSION: Participation in support groups and sharing of emotional expression, thoughts and ideas help the caregivers deal with their physical and psychological demands related to the caregiver load. As such, intervention strategies offered to caregivers in the support groups appear to positively contribute to the family with a psychotic patient and improve the quality of life of both patients and their main caregivers.
